Common mode chokes (CMC) are a type of electronic component used to ensure that noise from a signal line is properly filtered out before it reaches the load circuit. The HM86-10620LFTR is an example of such a component. It is designed for use in high power switched-mode power supplies, especially those with active components such as IGBTs and MOSFETs. This article will explore its application field and working principle.

HM86-10620LFTR is designed to filter out common mode noise in switch power supplies and other high-power switching circuits. It is a surface-mount component that can be mounted on a printed circuit board. The component has a low effective inductance of 0.9 μH and can handle up to 25A of current. This makes it well-suited for applications that require a high level of noise suppression but still need to maintain high efficiency and low standby energy consumption.

The HM86-10620LFTR is designed to filter out common mode noise by using a combination of inductors, capacitors, and resistors. The inductors act as a high-frequency pass filter, allowing low-frequency signals to pass through while blocking unwanted frequencies. The capacitor and resistor network are used to provide additional filtering and reduce any residual noise. This combination of components effectively filters out any common and differential noise present in the signal path.

The HM86-10620LFTR is an excellent choice for applications that require high-frequency operation and noise suppression, such as switched-mode power supplies. The component’s low inductance and high current handling make it highly efficient and well-suited for applications that require high efficiency and low power consumption. Additionally, the component is also suitable for noise suppression in signal and data lines, as well as in automotive electronics.

The working principle of the HM86-10620LFTR is quite simple. The inductors act as low resistance pass filters, allowing the desired low-frequency signals to pass through while effectively blocking any high-frequency noise. The capacitors and resistors then provide additional filtering for residual noise. This combination of components is effective in filtering out any noise present in the signal path and ensures that the signal reaching the load circuit is pure and free of interference.

In summary, the HM86-10620LFTR is an excellent choice for applications that require high-frequency operation and noise suppression. Its low effective inductance and high current handling make it highly efficient and enable it to filter out any common and differential noise present in the signal path. Additionally, the component is suitable for noise suppression in signal and data lines, as well as in automotive electronics. The combination of inductors, capacitors, and resistors provides an effective solution for filtering out unwanted noise and ensuring that the signal reaching the load circuit is free of interference. This makes it an ideal choice for a variety of applications.
